All aluminium structure
Robust frame with hard anodised aerometal beam and Z-axis offers temperature consistency as well as a reduced mass of moving parts and force of inertia to ensure high accuracy during high-speed movement.
Patented triangular beam
The triangular beam design offers a lower centre of gravity, better stiffness and more reliable motion compared to rectangular and cross beams.

Integral dovetail guide way
Integral dovetail guide way on Y-axis reduces the machine weight and helps prevent motional swings during the inspection process to ensure measuring accuracy and stability.
Self-cleaning air bearings
All three axes run on high-precision self-cleaning air bearings, providing smooth movement that reduces wear on the guide ways to maximise equipment durability and minimise repair costs.

High-precision optical scales
European-import, high-precision optical scales installed with one end fixed and the other freely extensible ensures linear expansion and contraction with temperature changes to mitigate the impact of thermal deformation.

DC servo motors
All three axes are driven by DC servo motors, providing stable movement and exact positioning to support accurate probe location and overall measurement.

Specially-designed control system
The IDC-I control system, designed by Hexagon Metrology specifically for the CROMA range, improves the dynamic performance and measuring capabilities of the machine.
